Brittany Murphy: Big Lips, Low Class

According to the New York Post, Murphy is driving the crew on her new movie crazy. Her behavior on the set of Across the Hall has gone from bad to worse, in large part due to Britt's outrageous, diva-like demands.

"She's extremely difficult. When she gets to the set, it comes to a grinding halt. She's so hot and cold, you never know," says a spy.

Wow. We never would have pegged ol' Hot Lips for a prima donna, but this is the celebrity news business. Nothing surprises us anymore.

According to the Post, Brittany Murphy insists on having diagonally cut peanut butter and jelly sandwiches with the crusts removed.

"She needs one every hour. It's painstaking - her assistant takes about a half an hour making each one," said one crew member.

Compounding problems is Murphy's ever-present bad seed of a husband, Simon Monjack, who lurks around the set and intervenes so much that producers had to call a meeting to discuss how to deal with him.

That's bad, but we're just surprised Simon Monjack hasn't found a way to liquidate Brittany's bank accounts and flee the country by now.
